Do high-end Ryzen chips need liquid cooling?
> ... this means that the base memory controller in the silicon should be able to support ECC. We know that it is disabled for the consumer parts, but nothing has been said regarding the Pro parts. ECC should be a standard feature. If you don't want it you don't have to use it but to disable simply for market segmentation is lame.
Considering previous AMD chips could use ECC I hope it's true this time as well. AMD's CEO Dr. Lisa Su has an AMA later today, we should probably ask her: https://www.reddit.com/r/Amd/comments/5vl431/its_happening_a... Might as well ask her about the possibility of coreboot if we are at it.

I haven't found one yet, but as the chip is rated at 65W and the i7 7700k at 91W, it's pretty likely to draw less (at load anyway). I'd be curious to see what they draw whilst idle though.
After having a look at some of the links posted, it looks like the power draw is slightly higher than the i7 7700k in most tests, although lower in some. Looks like my assumption based on the TDP was a bit off (also my misapprehension that TDP is power draw, whoops) :)
Do they ever do compiler speed tests or boot speed tests? Which of the existing ones would be most similar?
GCC is part of spec2006, which they optimize for. But the actual compilers people use (IE not that version of GCC) are rarely well-optimized for CPU. In fact, most compiler profiles are not flat yet, and where your compilation takes a long time, it's because some optimization or algorithm has gone nuts and needs to be fixed. Until that kind of state of the world changes, measuring compile time is IMHO, a bit pointles…

That'd be a fun test, too. One would need to control for disk io but definitely useful. I wonder how many HN readers run FBSD
FreeBSD 12.0-CURRENT on this very laptop. I'm going to build an 1800X-based box in a few weeks (for games; planning to run Steam on a GNU/Linux distro), I'll want to see `make -j16 buildworld` for sure.

According to AMD: "ECC is not disabled. It works, but not validated for our consumer client platform." https://www.reddit.com/r/Amd/comments/5x4hxu/we_are_amd_crea...
btw: someone asked about coreboot: https://www.reddit.com/r/Amd/comments/5x4hxu/we_are_amd_crea...
AMD Ryzen 1800X (Summit Ridge): 3.6 GHz (4.0 GHz Turbo) over 16 threads 15,812 Passmark for ~$500 ----- Intel i7-7700K (Kaby Lake): 4.2 GHz (4.5 GHz Turbo) over 8 threads 12,321 Passmark for ~$350 ----- Intel Core i7-6850K (Broadwell E): 3.6 GHz (4.0 GHz Turbo) over 12 threads 14,500 Passmark for ~$575 ----- Competition is back. Ya!
And that's only CPU prices, don't forget mainboards, which are overpriced on the Intel X99 side!

But it's still losing in every web and office single threaded benchmark. EDIT: compared to 7700k that costs about the same
Or, seen another way (better representation of the overall reality): The 7700k is losing in all aspects below w.r.t. the Ryzen 7 1800X, except absolute single-threaded perf. Intel is losing in: - absolute multi-threaded performance - relative multi-threaded performance per $ - memory bandwidth - L3-cache bound workloads (AMD has twice more L3) - price of motherboards

What means validated in this case? It's not certified by AMD to work, so depending on the memory and motherboard combination it could work, or if you are unlucky it doesn't work? btw: someone asked about coreboot: https://www.reddit.com/r/Amd/comments/5x4hxu/we_are_amd_crea...

Who buys a $350+ processor with 8C/16T for web/office?
